Angel in bronze lifted through gate (7)
I believe the answer is:
donator
'angel' is the definition.
(thesaurus)
'bronze lifted through gate' is the wordplay.
'bronze' becomes 'tan' (both can mean to get a sun tan).
'lifted' shows that the letters should be reversed in order (going up in down clue).
'through' is an insertion indicator (inserted letters go through the word).
'gate' becomes 'door' (I am not sure about this - if you are sure you should believe this answer much more).
'tan' in reverse letter order is 'nat'.
'nat' inserted into 'door' is 'DONATOR'.
'in' is the link.
Can you help me to learn more?
(Other definitions for donator that I've seen before include "Giver" , "One will give" , "benefactor!" , "Someone giving" , "Presenter" .)
